OPTIMIZING THE CHARACTERISTICS OF NEW HIGH-RESOLUTION SILVER-HALIDE MATERIALS FOR COUNTERPROPAGATING RECORDING IN A WIDE VISIBLE REGION

This paper describes the dependence of the diffraction efficiency and sensitivity on the exposure conditions, the synthesis conditions, and the chemical-photographic processing when reflective holograms are rec orded with continuous radiation in the red, green and blue regions of the spectrum. Conditions are determined that ensure sensitivities of a bout 10(-4) J/cm(2), which is more than a factor of 10 better than the sensitivity of previously known materials.
